The installation of equipment 1 Open the box to check A.If the type of equipment in the package is identical with the ordered type. B.If the type of equipment in the nameplate is identical with the ordered type. C.If the documents in packing list are complete. D.If the fittings in packing list are complete. E.If there is damaged electric component in package. 2.The installation of control panel BH BH series of variable frequency timing water supply equipment www.eastpump.com E-mail:eastpump@163.net A M B N C When the variable frequency timing constant voltage water supply system is in the automatic operating condition, the pressure sensor on the water supply pipe net collects its pressure data incessantly, and change it to normal electrical signal, then transport it to digital PID adjuster (there are two kinds, one is in the transducer, the other is out installed separately, and connected with transducer). When there is programmable controller in control panel, PLC controls the operation quantity of water pump according to the signal which transported by PID adjuster. When the required water is increased, and the pressure of pipe net is reduced(Measured value is lower than set value), PID adjuster increases the output frequency of transducer, and the revolving speed of water pump's motor is increased, if its speed up to the upper limit speed, the pressure of pipe net(measured value) is lower than the set pressure(set value), PID adjuster will give adding pump signal to programmable controller, and it will start the other water pump which is in stop condition; whereas, when the required water is reduced, and the pressure of pipe net is (Measured value is lower than set value) increased, PID adjuster decreases the output frequency of transducer, and the revolving speed of water pump's motor is reduced, if its speed down to the lower limit speed, the pressure of pipe net(measured value) is higher than the set pressure(set value), PID adjuster will give decreasing pump signal to programmable controller, and it will stop the other water pump which is in operation condition. After continual dynamic adjustment, the pressure of pipe net will keep constant. When there is little flow jockey pump in variable frequency timing constant voltage water supply system, it has three kinds of service. First is that main pump keeps variable frequency operation, jockey pump keeps power frequency operation: When the required water is less than the flow of jockey pump, main pump will stop, jockey pump will keep power frequency operation; When the required water is more than the flow of jockey pump, main pump will keep variable frequency operation, jockey pump will stop. Second is that main pump keeps power frequency operation, jockey pump keeps variable frequency operation: When the required water is less than the flow of jockey pump, main pump will stop, jockey pump will keep variable frequency operation; When the required water is more than the flow of jockey pump, main pump will keep variable frequency operation, jockey pump will stop. Third is that main pump keeps variable frequency operation, jockey pump keeps variable frequency operation: When the required water is less than the flow of jockey pump, main pump will stop, jockey pump will keep variable frequency operation; When the required water is more than the flow of jockey pump, main pump will keep variable frequency operation, jockey pump will stop. When there is stable voltage tank in variable frequency timing constant voltage water supply system, if the main pump and the little flow jockey pump are stop for losing water, the stable voltage tank can keep user's required water and supply the normal leakage of pipe net, to keep constant pressure. The time is determined by the valid cubage of the stable voltage tank. A.For heat emission and repair, it should keep a certain space between the control panel and wall or other things. Generally speaking, the back distance is 800mm from wall, the side distance is 500mm from wall. B.The control panel should be placed on the fixed baseplate. As the following drawing, the control panel is placed on the concrete baseplate, the height of 'M' is about 300mm, the length is as same as the 'B' length of the control panel, the width is as same as the 'C' width of the control panel; the depth of the middle cable tank is about 200mm, the length is as same as the 'B' length of the control panel, the width is about 170mm~300mm. C.The fixed baseplate of control panel also should have the special earthing device. 3 BH BH series of variable frequency timing water supply equipment www.eastpump.com E-mail:eastpump@163.net 2 3 1 8 9 10 11 7 6 5 5 6 7 A , 4 30-50cm 10-30cm 4 Connection require and methods for inlet/outlet terminal of control panel Connection requirement: Terminal block pressure feedback terminal block of control panel level sensor terminal block of control panel water tank wall Discharge pipe lower dynamic point upper dynamic point BH BH series of variable frequency timing water supply equipment www.eastpump.com E-mail:eastpump@163.net 2 3 1 8 9 10 11 7 6 5 no-negative pressure stable flow tank Transmissible pressure gauge connection drawing A of pressure sensor Transmissible pressure gauge connection drawing B of pressure sensor A Connection method A.Float level switch should be fixed in a proper position of cistern, detailed installing dimension refers to the left drawing. Any other things can not be in its radial scope, otherwise it will block and control its movement. The safe voltage on float level switch is Ac24v. B After fixing float level switch, we must assure that the height of water level should cover water pump impeller.
